  # Turn off some warnings that I've just found too noisy.
  #
  #  - 4244, 4267: "possible loss of data" when narrowing an integer
  #    type (separate warning numbers for initialisers and
  #    assignments). Every time I spot-check instances of this, they
  #    turn out to be sensible (e.g. something was already checked, or
  #    was assigned from a previous variable that must have been in
  #    range). I don't think putting a warning-suppression idiom at
  #    every one of these sites would improve code legibility.
  #
  #  - 4018: "signed/unsigned mismatch" in integer comparison. Again,
  #    comes up a lot, and generally my spot checks make it look as if
  #    it's OK.
  #
  #  - 4146: applying unary '-' to an unsigned type. This happens once,
  #    in Untangle, and it's on purpose - but I haven't found any idiom
  #    at the point of use that reassures the compiler that I meant it.
  #
  #  - 4305: truncation from double to float. We use float all the time
  #    in this code base, and truncations from double are fine.
